Levitating Coffee Cup Prank Ad

15 seconds, vertical screen 9:16, iPhone native camera texture, single continuous shot, one-take, no editing, no jump cuts, no transitions. The reference video is only for referring to the rhythm and camera movement of "front-side floating performance in the first half, right-circling reveal of the mechanism in the second half," not copying the venue, landing stand, top subtitles, watermark, or characters from the reference video. The scene is an outdoor city sidewalk during the day, bright but not overexposed, with soft natural daylight, a real smartphone snapshot texture. Two adult women, like close friends, are playing a light prank on the roadside. Sidewalk is smooth, clean, and open; the main background is a non-reflective light-colored building wall and a small amount of natural greenery, no street-facing glass windows, mirrored doors, or reflective metal walls. Occasionally one or two ordinary adult passersby walk naturally across in the distance, at least 4 meters away, not stopping, not watching, not looking at the camera, not imitating actions, and not crossing the core performance area of the coffee cup, boom arm, @1, and @2. The core props of the frame are always only one coffee cup, one gray horizontal boom arm, and one white slip of paper.

[The only physical mechanism set up from the first frame] Exactly one rigid straight gray horizontal boom arm, parallel to the floor, extends forward from @2’s waist toward the camera, with the coffee cup fixed at its front tip. The same boom already exists at frame 1 and never appears, grows, extends, changes direction, or changes shape later. The only gray boom arm is about 80 cm long and 2.5 cm in diameter, always straight and parallel to the ground, maintained at height between @2's waist and chest. The front end of the boom arm only connects to the exact center of the back of the coffee cup, with the connection point completely hidden behind the cup; no short poles or joints protrude from the left or right sides of the cup; the back end is completely covered and fixed by @2's forearm and sleeve held close to the abdomen. The boom arm does not touch the ground, wall, or ceiling. The space between the bottom of the cup and the ground is always clearly visible and empty. At the opening, the camera optical axis, the center of the coffee cup, the long axis of the gray boom arm, and @2's torso center are strictly on the same depth-of-field straight line. The coffee cup completely hides the boom arm behind it from the front, so even though the mechanism exists from the first frame, it is completely invisible from the front; it is only gradually seen later due to parallax as the camera circles to the right, not because a new pole is generated midway.

A medium blue and white takeout coffee cup, royal blue body, white lid, only the clear white English word "JOHN" in the center of the cup body. No real brands or antler designs. The cup stays fixed in the same spatial position throughout, remaining vertical, same size, not drifting, rotating, or deforming. There is only this one cup in the entire film. The white slip of paper is 14 cm wide and 10 cm high, already fixed to the bottom side of the middle section of the boom arm with two short pieces of transparent tape from the first frame. The top edge of the paper is flush with the arm, and the vertical plane of the paper is parallel to the long axis of the boom arm: from the front at the start, only the very narrow edge of the paper is visible; as the camera circles to the right, the front of the paper naturally unfolds with parallax. The paper has only two lines, the first line must not be broken:

@1 wears @1 reference clothing, always stands in the left third of the frame, feet stationary, body and head never crossing the center line of the screen, never walking in front of the coffee cup or between the cup and @2. @1 only extends her hands from the left toward the top and bottom of the cup for performance; her palms are always about 10 cm from the cup, not touching it. She is playful, lively, smart, and agile like she's teasing a friend on the street: naturally relaxed with a slight side turn, soft wrist flick, fingers slowly spreading. Her eyes move naturally between the cup, @2, and the camera, occasionally raising an eyebrow, showing a mischievous smile she can't help but let out, and giving the camera a short playful wink when successfully demonstrating "levitation." Not a formal commercial pose, not stiff, not vulgar, no exaggerated twisting, no funny faces.

@2 wears @2 reference clothing, feet stationary, always standing on the same depth-of-field axis directly behind the coffee cup. @2 hides the back end of the boom arm with her forearm and sleeve held close to her abdomen, keeping the arm fixing the mechanism, her body, and position stationary throughout; however, in the first 5 seconds when her face is still clearly visible, she acts like she's playing along with her friend's prank: first staring seriously at the cup, then eyebrows raised, eyes slightly widened, pretending to be surprised despite knowing the mechanism; briefly pursing her lips to hold back a laugh when seeing @1 blow air, then looking at @1 and the camera with an innocent humorous gaze that says "almost got me." There is a familiar, relaxed rapport between them. @2 only performs facial and slight eye changes, not speaking, not opening her mouth wide, not shaking her head, not shrugging. After 5 seconds, the camera zooms in, and @1 and @2's faces are naturally cropped out of the frame.

[Strict continuous timeline]
0—2 seconds: Front medium wide shot, no camera horizontal movement. The cup is in the center of the frame, @1 is fixed on the left, and @2 is directly behind the cup. The complete sidewalk pavement under the cup is clearly visible. @1 has one hand above the rim and one below the bottom, no contact; she first looks seriously at the cup, then looks at @2 and the camera with the corner of her eye, raising an eyebrow with a playful expression of holding back a laugh. @2 cooperates with her friend, first staring seriously at the cup, then slowly raising eyebrows and widening eyes, putting on a humorous reaction of "wow, it actually floated." Neither of their bodies or feet moves. A passerby can naturally pass in the distance without looking at them or entering the main axis.

2—5 seconds: The camera remains in the same front position. @1's feet and body don't move, only performing three sets of clear, slow hand movements: the right hand passing horizontally over the cup rim; the left hand passing horizontally under the cup bottom; hands spreading out to show they are empty. She acts as if intentionally teasing @2, with the corners of her mouth starting to turn up; then she leans in from the left to blow air gently on the cup rim, looks at @2, then gives the camera a short playful wink, and finally frames the cup with both hands (one above, one below) with a small proud smile that says "How about that, pretty good, right?" @2's body and the arm fixing the boom stay absolutely still, only responding with expressions: first looking back and forth between the cup and @1, pursing lips to hold back a laugh when @1 blows air, and finally looking at @1 with an innocent humorous gaze that says "I'm just quietly watching you perform." They act like familiar friends naturally joking, not actors reciting lines. Throughout the 3 seconds, the cup, @2, and the camera optical axis remain collinear, with the boom completely hidden by the cup.

5—7 seconds: The camera moves slowly forward along the optical axis, no horizontal movement, no rotation, pushing from medium wide shot to a close-up about 45 cm from the cup. Autofocus locks on "JOHN." @1 and @2's faces gradually leave the frame, leaving only the cup, @1's hands, a small amount of clothing edges, and the empty ground under the cup. The boom is still invisible due to collinear obstruction.

7—10 seconds: The camera rotates slowly and evenly to the right about 70 degrees around the coffee cup as a fixed center at the same height and distance, taking a full 3 seconds, no camera whip. Neither the cup nor the boom moves. At 7—8 seconds, only a small section of the gray crossbar behind the cup is seen due to slight parallax; at 8—9 seconds, about half is seen; at 9—10 seconds, the same full boom arm is seen extending straight from the back of the cup toward @2's abdomen. It appears as a horizontal line in the frame, and the paper also gradually unfolds from its narrow edge. Faces no longer in frame.

10—12 seconds: Maintaining the same shot, the camera moves slowly along the side of the boom arm from the front of the cup toward the middle section. The coffee cup naturally retreats to the left edge, the only gray crossbar runs through the center of the frame, and the front of the paper gradually turns toward the camera. The focus shifts smoothly from the bar to the paper; the paper doesn't appear suddenly.

12—15 seconds: The camera reaches a close-up of the paper and stops moving. The paper occupies about 50% of the frame width, the gray boom arm runs horizontally behind the paper, and only a small part of the coffee cup remains on the left edge. The two lines of text are stable, upright, and clearly legible: "Your Ad Space / hf_20260723_023253_17d01f18-b189-45de-be9c-f30db6d27116."

15 秒，竖屏 9:16，iPhone 原生相机质感，单个连续镜头，一镜到底，无剪辑、无跳切、无转场。参考视频只用于参考“前半段正面悬浮表演、后半段向右绕行揭露机关”的节奏和运镜，不复制参考视频中的场地、落地支架、顶部字幕、水印和人物。 场景是白天的城市室外人行道，天气明亮但不过曝，柔和自然日光，真实手机随手拍质感。两位成年女性像关系很好的闺蜜一样，在路边临时开一个轻松的小玩笑。人行道平整、干净、空间开阔；主要背景是一面无反光的浅色建筑实墙和少量自然绿化，不出现临街玻璃橱窗、镜面门、反光金属墙。远景偶尔有一两名普通成年路人自然横向走过，路人距离主体至少 4 米，不停留、不围观、不看镜头、不模仿动作，也不穿过咖啡杯、悬臂、@1 与 @2 所在的核心表演区域。画面核心道具始终只有一个咖啡杯、一根灰色水平悬臂和一张白色纸条。 【从第一帧已经搭建好的唯一实物机关】 Exactly one rigid straight gray horizontal boom arm, parallel to the floor, extends forward from @2’s waist toward the camera, with the coffee cup fixed at its front tip. The same boom already exists at frame 1 and never appears, grows, extends, changes direction, or changes shape later. 唯一的一根灰色悬臂长约 80 厘米、直径约 2.5 厘米，始终笔直并与地面平行，保持在 @2 腰部至胸腹部高度。悬臂前端只连接咖啡杯背面正中央，连接点完全藏在杯后，杯子左右两侧没有突出的短杆或接头；后端最后约 10 厘米被 @2 紧贴腰腹的前臂和衣袖完全遮住并固定。悬臂不接触地面、墙壁或天花板。杯底到地面之间始终是清楚可见的完整空地。 开场时，镜头光轴、咖啡杯中心、灰色悬臂长轴、@2 躯干中心严格处在同一条景深直线上。咖啡杯从正面完整遮住其后方的悬臂，因此机关虽然从第一帧就真实存在，正面却完全看不见；后续只因摄影机向右绕行产生视差，才逐渐看到同一根悬臂，绝不是中途生成一根新杆。 中号蓝白外带咖啡杯，皇家蓝杯身、白色杯盖，杯身正中只有清晰白色英文“JOHN”。没有真实品牌 and 鹿角图案。杯子全程固定在同一个空间位置，保持竖直，大小不变，不漂移、不旋转、不变形。全片只有这一个杯子。 白色纸条宽 14 厘米、高 10 厘米，从第一帧起就已经用两小段透明胶带固定在悬臂中段的下侧。纸条顶边贴杆，纸面所在的竖直平面与悬臂长轴平行：开场正面看时纸条严格侧对镜头，只露出极窄纸边；镜头向右绕到侧面后，纸条正面才随视差自然展开。纸条只写两行，第一行不得拆行： 您的广告位

，始终站在画面左侧三分之一处，双脚原地不动，身体 and 头部绝不越过画面中线，绝不走到咖啡杯正前方或咖啡杯与 @2 之间。@1 只从画面左侧把双手伸向杯子上下方表演；手掌与杯子始终保持约 10 厘米距离，不接触杯子。她像在街边逗闺蜜开心一样俏皮、活泼、聪明灵动：自然放松地轻微侧身，柔软翻腕，十指缓慢张开。她的眼神在杯子、@2 与镜头之间自然移动，偶尔轻挑一侧眉毛，露出忍不住想笑的顽皮笑容，并在成功展示“悬浮”时给镜头一个短促俏皮的眨眼。不是正式商业摆拍，不端着，不低俗，不夸张扭动，不做鬼脸。 @2

，双脚不动，始终站在咖啡杯正后方的同一景深轴线上。@2 用贴近腰腹的前臂和衣袖隐藏悬臂后端，固定机关的手臂、身体 and 站位全程不动；但在脸部仍清楚可见的前 5 秒里，她像正在配合闺蜜恶作剧：先故作认真地盯着杯子，随后眉毛上扬、眼睛略微睁大，明知机关却装作吃惊；看到 @1 吹气时短暂抿嘴憋笑，再以“差点被你骗到”的无辜幽默眼神看一眼 @1 和镜头。两人之间有熟悉、放松的默契感。@2 只做面部和轻微眼神变化，不说话、不张大嘴、不摇头、不耸肩。5 秒后镜头推近，@1 与 @2 的脸自然被裁出画面。 【严格连续时间轴】 0—2 秒：正面中全景，摄影机完全不横移。杯子位于画面中心，@1 固定在左侧，@2 位于杯子正后方。杯底下方完整人行道路面清楚可见。@1 一手停在杯口上方、一手停在杯底下方，不接触；她先故作认真地看杯子，再用眼角看向 @2 和镜头，轻挑一侧眉毛并露出忍笑的顽皮表情。@2 配合闺蜜先认真盯着杯子，随后眉毛慢慢抬起、眼睛略微睁大，装出“居然真的浮起来了”的幽默反应。两人的身体 and 脚都不移动。远处可以有一名路人自然经过，但不看她们，也不进入主体轴线。 2—5 秒：摄影机仍在同一正面位置。@1 的脚 and 身体不移动，只做三组清楚、缓慢的手部动作：右手从杯口上方横向掠过；左手从杯底下方横向掠过；双手向外张开展示空手。她像在故意逗 @2，嘴角逐渐忍不住上扬；随后从左侧靠近杯口轻轻吹气，吹气后先看 @2 一眼，再看向镜头短促俏皮地眨一次眼，最后带着“怎么样，厉害吧”的得意小笑容用双手一上一下框住杯子。@2 的身体 and 固定悬臂的手臂保持绝对不动，只用表情接梗：先在杯子 and @1 之间来回看一眼，@1 吹气时抿嘴憋笑，最后用“我就静静看你演”的无辜幽默眼神看向 @1。两人表现得像熟悉的闺蜜自然打趣，不像演员背台词。整个 3 秒内杯子、@2 与摄影机光轴保持共线，悬臂完全被杯子遮住。 5—7 秒：摄影机只沿光轴缓慢向前推近，不横移、不旋转，从中全景推进到距离杯子约 45 厘米的近景。自动对焦锁定“JOHN”。@1 and @2 的脸逐渐离开画面，只保留杯子、@1 的双手、少量服装边缘以及杯底下方的空地。悬臂仍因共线遮挡而不可见。 7—10 秒：摄影机以咖啡杯为固定旋转中心，在同一高度、同一距离缓慢均匀向右绕行约 70 度，用完整 3 秒完成，不甩镜。杯子 and 悬臂都不动。7—8 秒只因轻微视差露出杯后的一小截灰色横杆；8—9 秒看到约一半；9—10 秒看到同一根完整悬臂从杯背面笔直延伸至 @2 腰腹方向。它在画面中呈水平横线，纸条也从极窄纸边逐步展开。人物面部不再入镜。 10—12 秒：保持同一个镜头，摄影机在悬臂侧面沿着悬臂从杯子前端缓慢移动到中段。咖啡杯自然退到画面左边缘，唯一的灰色横杆贯穿画面中央，纸条正面逐渐转到镜头前。焦点从横杆平滑转移到纸条，纸条不是突然出现。 12—15 秒：摄影机到达纸条近景后停止位移并稳住。纸条约占画面宽度 50%，灰色悬臂从纸条背后水平贯穿，咖啡杯只在左边缘保留少量。两行文字稳定、端正、清晰可读：“您的广告位
